#If TF_IN_AUTOMATION is set to any non-empty value, 
#Terraform adjusts its output to avoid suggesting specific commands to run next
export TF_IN_AUTOMATION

#TF_DATA_DIR changes the location where Terraform keeps its per-working-directory data,
#such as the current remote backend configuration.

#Set TF_REGISTRY_DISCOVERY_RETRY to configure the max number of request retries the remote registry client will attempt 
#for client connection errors or 500-range responses that are safe to retry

#The default client timeout for requests to the remote registry is 10s. 
#TF_REGISTRY_CLIENT_TIMEOUT can be configured and increased during extraneous circumstances.

#If TF_IGNORE is set to "trace", Terraform will output debug messages to display ignored files and folders.
